Graphite is a node-based visual design environment that integrates vector illustration, raster image processing, and motion graphics generation into a single platform. It utilizes a functional reactive pipeline and a data-flow execution model to propagate state changes through a graph of interconnected nodes, allowing users to construct complex, automated design workflows. The platform distinguishes itself through a context-aware evaluation engine that injects runtime metadata—such as coordinate data and loop indices—directly into the node graph. This enables the creation of procedural geomet
Graphite is a node-based vector graphics and design editor with procedural capabilities, fitting the category well though it currently lacks some traditional UI/UX prototyping and collaboration features.
This project is a virtual whiteboard component and vector graphics editor designed for creating diagrams with a hand-drawn aesthetic. It provides a canvas-based drawing engine that can be embedded directly into web applications, allowing users to manipulate shapes, upload images, and export visual data into standard formats like PNG, SVG, or JSON. The platform distinguishes itself through a real-time synchronization layer that supports multi-user collaboration across distributed environments. This engine utilizes end-to-end encryption to secure shared sessions and employs a local-first data p
Excalidraw is a collaborative vector-based whiteboard and diagramming tool featuring real-time synchronization, though it leans towards hand-drawn sketching rather than precise UI/UX prototyping.
SVGEdit is a browser-based SVG editor and canvas engine used for creating and modifying scalable vector graphics files. It provides a web interface for vector design and functions as an embeddable editor that can be injected into HTML elements within other web applications. The project allows for the development of custom SVG tools and the construction of bespoke vector graphics editors by utilizing its standalone drawing engine.
SVGEdit is a browser-based vector editor and canvas engine, but it is primarily an embeddable component for building custom SVG tools rather than a full-featured UI/UX prototyping and design application with collaboration features.
Rnote is a vector-based note-taking and drawing application designed for capturing handwritten input. It functions as a digital workspace that records stylus pressure and movement to create sketches and notes, storing them as mathematical paths rather than pixels to allow for infinite scaling and non-destructive editing. The application provides a flexible canvas environment that supports infinite scrolling and various page layouts. Users can organize their work using a layer-based system, which allows for the independent manipulation and ordering of individual strokes, shapes, and background
Rnote is a vector-based drawing and note-taking application rather than a dedicated UI and UX prototyping tool, making it a neighbouring graphics utility rather than the requested design suite.
Whitebophir is a collaborative whiteboarding application designed for real-time visual collaboration. It enables multiple users to brainstorm and create content together on a shared virtual canvas using freehand sketching, geometric shapes, and text labels. The platform focuses on private workspace management, allowing the creation of restricted boards via unique URLs and token-based access control to manage editing permissions. It integrates real-time state synchronization for drawing updates and a built-in chat system for text communication between collaborators. The workspace includes too
Whitebophir is a collaborative whiteboarding tool for real-time sketching rather than a vector-based UI and UX design editor with prototyping and component libraries.
Etherpad-lite is a web-based platform designed for real-time collaborative text editing. It enables multiple users to view and modify the same document simultaneously, utilizing an operational transformation engine to synchronize content across all connected client sessions. The platform distinguishes itself through a modular, plugin-based architecture that allows for the integration of third-party extensions to introduce custom functionality. It provides a comprehensive programmatic interface for document management, allowing users to automate the creation, update, and retrieval of text docu
This repository is a real-time collaborative text editor rather than vector-based graphic design or UI/UX prototyping software, making it a completely different category.
Semi Design is a React UI component library and design token system used to build web application frontends. It provides a collection of pre-built interface elements and a framework of visual constants to maintain consistent branding across a product. The project features a design-to-code workflow that converts visual design drafts into production-ready React code and stylesheets. It includes an internationalization framework for adapting interfaces to different languages and text layouts, as well as a web component wrapper to isolate UI elements for use in SDKs and browser plugins. The libr
Semi Design is a React UI component library rather than a standalone vector graphic design editor for UI and UX prototyping, making it a building block for web frontends rather than the tool requested.
This project is a React data table component integrated with shadcn/ui. It provides a set of tabular data grids that support sorting, filtering, and pagination. The implementation includes a virtualizing data grid and an infinite scroll table, which allow for the rendering of large datasets by loading records incrementally or displaying only the items visible in the viewport. It also functions as a real-time collaborative table, enabling multiple users to manage and edit shared datasets simultaneously. The component covers interactive data management and complex data visualization. This incl
This project is a React data table component rather than a vector-based UI and UX design application, making it the wrong category for graphic design work.
AndroidAssetStudio is a web-based toolset for creating launcher icons, action bar graphics, and notification assets for Android applications. It functions as a resource graphic suite for producing correctly sized images and icons that comply with Android system requirements and directory structures.
